Trial of Optimal Personalised Care After Treatment—Gynaecological Cancer (TOPCAT-G): A Randomized Feasibility Trial

Abstract: Objective This study aimed to evaluate the feasibility of completing a parallel-group randomized controlled trial to compare usual follow-up care for women who have completed treatment of gynecological cancer against a nurse-led telephone intervention, known as Optimal Personalised Care After Treatment—Gynaecological. Methods The unblinded trial aimed to recruit patients who had completed treatment of cervical, endometrial, epithelial ovarian, or vulval cancer within the previous 3 months at 3 North Wales hospitals. We randomized participants to either usual hospital-based follow-up or specialist nurse–led telephone education, empowerment, and structured needs assessment follow-up. The primary outcomes assessed the feasibility of running a larger trial including patient eligibility, recruitment and retention rates, and outcome measure completion. Secondary outcomes were generic and health-related quality of life and a patient self-report health service use (Client Service Receipt Inventory) data collected at 3 time points (baseline, 3 months, and 6 months). Results Of the 58 women screened, 44 were eligible (76%) and 24 (55%) were recruited and randomized (12:12 to control and intervention, respectively). One participant was lost to follow-up. Recruited participants had a mean (SD) age of 60 (11.2) years and were approximately 5 months from their initial diagnosis (mean [SD], 159 [58] days). Seventeen (71%) of the participants had an endometrial cancer diagnosis. All outcome measure completion rates exceeded 96%. Although not a core feasibility objective, analyses of outcome measures indicated positive changes in quality of life and well-being within the Optimal Personalised Care After Treatment—Gynaecological group; exploratory cost consequence analysis indicated that the nurse-led intervention had a mean total service use cost of £27 per patient (bootstrapped 95% confidence interval, −£290 to £240) lower than did the standard care group. Conclusion Eligibility, recruitment, and retention rates as well as outcome measure completion showed that the trial is feasible.

Development of an intervention to expedite cancer diagnosis through primary care: a protocol.

Abstract: Background GPs can play an important role in achieving earlier cancer diagnosis to improve patient outcomes, for example through prompt use of the urgent suspected cancer referral pathway. Barriers to early diagnosis include individual practitioner variation in knowledge, attitudes, beliefs, professional expectations, and norms. Aim This programme of work (Wales Interventions and Cancer Knowledge about Early Diagnosis [WICKED]) will develop a behaviour change intervention to expedite diagnosis through primary care and contribute to improved cancer outcomes. Design & setting Non-experimental mixed-method study with GPs and primary care practice teams from Wales. Method Four work packages will inform the development of the behaviour change intervention. Work package 1 will identify relevant evidence-based interventions (systematic review of reviews) and will determine why interventions do or do not work, for whom, and in what circumstances (realist review). Work package 2 will assess cancer knowledge, attitudes, and behaviour of GPs, as well as primary care teams’ perspectives on cancer referral and investigation (GP survey, discrete choice experiment [DCE], interviews, and focus groups). Work package 3 will synthesise findings from earlier work packages using the behaviour change wheel as an overarching theoretical framework to guide intervention development. Work package 4 will test the feasibility and acceptability of the intervention, and determine methods for measuring costs and effects of subsequent behaviour change in a randomised feasibility trial. Results The findings will inform the design of a future effectiveness trial, with concurrent economic evaluation, aimed at earlier diagnosis. Conclusion This comprehensive, evidence-based programme will develop a complex GP behaviour change intervention to expedite the diagnosis of symptomatic cancer, and may be applicable to countries with similar healthcare systems.

Lessons learnt from a discontinued randomised controlled trial: adalimumab injection compared with placebo for patients receiving physiotherapy treatment for sciatica (Subcutaneous Injection of Adalimumab Trial compared with Control: SCIATiC).

Abstract: Adalimumab, a biological treatment targeting tumour necrosis factor α, might be useful in sciatica. This paper describes the challenges faced when developing a new treatment pathway for a randomised controlled trial of adalimumab for people with sciatica, as well as the reasons why the trial discussed was stopped early. A pragmatic, parallel group, randomised controlled trial with blinded (masked) participants, clinicians, outcome assessment and statistical analysis was conducted in six UK sites. Participants were identified and recruited from general practices, musculoskeletal services and outpatient physiotherapy clinics. They were adults with persistent symptoms of sciatica of 1 to 6 months’ duration with moderate to high level of disability. Eligibility was assessed by research physiotherapists according to clinical criteria, and participants were randomised to receive two doses of adalimumab (80 mg then 40 mg 2 weeks later) or saline placebo subcutaneous injections in the posterior lateral thigh. Both groups were referred for a course of physiotherapy. Outcomes were measured at baseline, 6-week, 6-month and 12-month follow-up. The main outcome measure was disability measured using the Oswestry Disability Index. The planned sample size was 332, with the first 50 in an internal pilot phase. The internal pilot phase was discontinued after 10 months from opening owing to low recruitment (two of the six sites active, eight participants recruited). There were several challenges: contractual delays; one site did not complete contract negotiations, and two sites signed contracts shortly before trial closure; site withdrawal owing to patient safety concerns; difficulties obtaining excess treatment costs; and in the two sites that did recruit, recruitment was slower than planned because of operational issues and low uptake by potential participants. Improved patient care requires robust clinical research within contexts in which treatments can realistically be provided. Step changes in treatment, such as the introduction of biologic treatments for severe sciatica, raise complex issues that can delay trial initiation and retard recruitment. Additional preparatory work might be required before testing novel treatments. A randomised controlled trial of tumour necrosis factor-α blockade is still needed to determine its cost-effectiveness in severe sciatica. Current Controlled Trials, ISRCTN14569274 .
